A well-constructed object model can improve the application performance by eliminating the table joins, decreasing the round trips, and the same.
The Client programs, involving the PL/SQL programs, can declare the objects and collections, and pass them as parameters, store them in the database, recover them, and so on. Also, by encapsulating the operations with data, the object types move data-maintenance code out of the SQL scripts and PL/SQL blocks into methods.
